"With tiny, high pixel count chips noise is always going to be an issue, and to a large degree this is more a test of the effectiveness (both measurable and visible) of a camera's noise reduction system. Designers have to balance the desire to produce smooth, clean results with the need to retain as much detail as possible (if you blur away the noise, you blur away image detail too).

It's interesting to compare the FZ50 (with it's Venus III engine) and its predecessor the FZ30. Noise is visibly lower, but (using the default NR setting as here) you're sacrificing even more detail, producing results that - though very clean and smooth - are actually softer looking and less detailed, despite the extra two million pixels. As our studio shot shows, with good light and fairly contrasty detail, detail is actually fairly well preserved even at ISO 400 (the luminance NR is quite low), but once you get low contrast fine detail you can see the effect of the heavy chroma NR even at ISO 100."

Majitel FZ-50 s Tebou asi měnit nebude, protože foťák je vždy o komplexu funkcí a vlastností a nikoliv o šumu, jak se stále dokola snaží někteří přesvědčovat v internetových diskuzích.
